What is the proper way of add cache value on ionic-cache?

Question

I tried to read the https://github.com/Nodonisko/ionic-cache readme, but I cant understand how to store value on it.

I tried to put this.cache.getOrSetItem('key', 'value'), but I am just getting this error Argument of type '"value"' is not assignable to parameter of type 'CacheValueFactory<{}>'. (typescript-tide) and got no idea what is CacheValueFactory.

Somebody can point please, for best documentation about this if there is any.

Thanks.

P.S. Just trying to learn Ionic framework.

Answer 1

According to your example, I think you are trying to get or set values and store in app memory. I suggest you could change your plugin to Ionic Native Storage. It is easy and simpler to user. The stored data will clear only if you clear data or cache on your mobile app settings or use clear()/remove() methods in your code.

Answer 2

You would use the this.cache.saveItem(key: string, data: any, groupKey?: string, ttl?: number) : Promise<any>

Where this.cache.saveItem('myUniqueCacheKey', 'mySavedResponseValueMayBeJSON') is a simple example.

this.cache.getOrSetItem is to use when one is uncertain about the existance of a cached key, and one wants it to be written, if it does not exist. To understand what needs to be written one needs to build a CacheValueFactory. That is another topic though.
